Dear @saralandeira
When testing on Chrome, Safari and Firefox the Project Thumbnails appear ( I also tested on a Mobile device to be sure ):

They do load slowly. This may be why you see white space?
Also Lazy loading is on and requires scrolling down make content appear for me.

Maybe i have misunderstood sorry @saralandeira but i am able view the Thumbnail content. It appears though slowly, Using smaller file sizes may be a solution for you.
Talk soon @saralandeira & have a great day š
